A couple have told of their horror after discovering an earwig inside a sealed bag of bread rolls picked up on their weekly supermarket shop.

Jane Naisbett, who bought the rolls at an Asda Superstore in Sunderland while shopping with her partner Gary MacPhail, said she was 'terrified' when she spotted the bug as she prepared to make some sandwiches.

'If I was partially sighted I might have eaten it,' the 53-year-old said.

Shock: The couple say there is no way the earwig could have got into the bag after they brought it home as it was still completely sealed

The disgusted couple, from Hendon in Sunderland, complained to the store on the Leechmere Road Industrial Estate, but Asda bosses say they could not fully investigate because the pair did not leave the item with them.

An inspection has since been carried out at the bakery but the supermarket said it found no evidence of insects.
